- Primary outcomeThe primary outcome parameter in this study is the time to reach half incremental area under the curve (t iAUC) for the sum of all amino acids (total AA) comparing product A to product B.
- Secondary outcomeThe secondary outcome parameters of this study are:
The (incremental) maximum amino acid concentration ((i)Cmax), (incremental) area under the concentration curve ((i)AUC) and t iAUC comparing all study products for total AA
Gastric emptying half time (t1/2), Cmax, and time until Cmax is reached (Tmax) and AUC (plasma concentrations of paracetamol) comparing all study products
Satiety questionnaire

- Brief summaryThe purpose of the current study is to gain knowledge regarding amino acid bioavailability of different proteins and protein mixes. Secondly, we aim to study the impact of different proteins on gastric emptying and postprandial fullness and satiety.

This is a randomized, controlled, double-blind, crossover, single-centre study which aims to include 13 healthy older subjects (age 65 years or older) with a minimum of 4 subjects for each sex.

Six different study products will be investigated: - 4 seperate proteins
- two mixes of these proteins
- Main changes (audit trail)
- RECORD2-sep-2015 - 4-nov-2015
